TURFING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 409,900, dated August 27, 1889. Application filed December 15, 1888. Serial No. 293,671- (ModeL) To all whom it may concern.-

Be it known that I, MELVILLE C. AYER, of Biddeford, in the county of York and State of Maine, have invented a new and Improved Feeding Device for Turfing orRug Machines, of which the following is a full, clear, and exact description.

The invention relates to embroidery-machines such as shown and described in Letters Patent No. 251,381, granted to E. Ross, December 27, 1881.

The object of the invention is to provide a new and improved device specially intended for turfing or rug machines, and serving for automatically feeding the machine forward, being very simple and durable in construction and very effective in operation.

The invention consists in certain parts and details and combinations of the same, as will be hereinafter described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied. Fig. 2 is an edge elevation of the same. Fig. 3 is a sectional side elevation of the same. Fig. 4 is an inner edge elevation of the looper-block, and Fig. 5 is a like view of the needle-block.

The turfing implement is provided with the usual needle-block A and the looper-block B, mounted to slide one on the other by suitable means. The needle-block A is provided in its lower end with the usual needle 0, and in the looper-block B is held the looper D, extending into a groove E, formed in the said looper-block at its inner edge. The looper D is pivoted at F in the groove E and extends at its inner upper end into the slot H, formed in the arm H of a bell-crank lever I, pivoted at I in the upper end of the groove E. The other arm J of the bell-crank lever I extends into a groove A, formed in the needle-block A. The arm J operates between the two fixed pins K and K, extending transversely in the needle-block A through the slot A, as is plainly shown in Fig. 3. The swinging motion of the looper D is limited by a set-screw G, screwing in the lower end of the looperblock B. The lower end of the looperD is slightly curved, as shown at D in Fig. 4. A spring L is held on the pivot F and presses against one side of the looper D, so as to hold the same in place in its groove E in the looperblock B.

The operation is as follows: The operator takes hold ofrthe needle and looper bllocks A and B and slides one on the other in the usual manner, so that the needle 0, with its thread, passes through the material to be operated on with the lower vend of the looper D resting close to the needle and holding the thread in place on the material. When the needleblock A is now moved upward, so as to withdraw the needle 0 from the material, the block A in its upward movement brings the pin K against the arm J of the bell-crank lever I, so that the latter is swung and moves the arm H outward toward the block A. As the lower end of the looper D rests firmly on the material, the block B is swung by the action of the bell-crank lever I on the upper end of the looper D, so that both blocks A and B swing forward until the lower'end of the looper D strikes against the end of the set-screw G. 'When the needle-block A is now moved downward the needle 0 passes into the material to be operated on at a distance from the former aperture, soas to form a new loop below the material. When the block A in its downward movement strikes with the pin K against the arm J of the bell-crank lever I, the arm H of the said bell-crank lever swings inward so that the looper D is swung with its lower end against the needle 0. The block B is then pressed, with the looper D, onto the thread on the material, after which the block A is again moved upward so as to withdraw the needle from the material, and the above-described operation is repeated.

It will be seen that the turfing implement is moved forward at every upstroke of the needle-block A, and this distance is regulated 5 by the set-screw G and can consequently be increased or diminished at will. The loops on the material formed by the needle (0 and its thread are consequently equal distances apart.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A turfing implement comprising the sliding needle and grooved looper-blocks held face to face and recessed longitudinally on their adjacent faces, the needle secured rigidly to the inner face of the needle-block, the looper pivoted in the groove of the looperblock to rock toward and from the needle, a lever engaging the said looper and projecting into the path of the needle-block and positively operated by said block, substantially as set forth.

2. The combination, with a grooved needleblock carrying the needle and provided with fixed pins extending transversely through said groove, of a looper-block held to slide on the said needle-block, a looper pivotedin the said looper-block, a bell-crank lever f ulcrumed in the said looper-block and engaging with one arm the said looper and having its other arm extending between the :said fixed pins in the needle-block, substantially as shown and described.

3. The combination, with a grooved needleblock carrying the needle and provided with fixed pins extending transversely through said groove, of a looper-block held to slideon the said need1e-block,a looper pivoted in the said looper-block, a bell-crank lever fulcrumed in the said looper-block and engaging with one arm the said looper and having its other arm extending within the range of the said fixed pins in the needle-block, and a set-screw held in the said looper-block and serving to limit the motion of the said looper, substantially as shown and described.

MELVILLE C. AYER.
